Answer:
See explaination
Step-by-step explanation:
B. The equality relation on the real numbers is an equivalence relation.
This statement is true
C. If RR is a reflexive relation on a set S, then any two RR- related elements of S must also be R2R2 related.
This statement is true
F. The less than or equal relation on the real numbers fails to be an equivalence relation because it is reflexive and transitive but not symmetric
This statement is true
H. If RR is an equivalence relation, then R2
This statement is true
It can be 15/8 if improper fraction or 1 7/8 if mixed number
Answer:
40) w = 32/3
41) x = 23/4
42) w = 1/12
Step-by-step explanation:
40) Real world problem:
If Lisa takes 
of the pie from a total of 
slices, then the remaining pie is 
. Find w.
So, the equation would become:
This can be written as:
This is equivalent to 
Since, the denominator is the same, the numerators can be added now.
Hence, the answer is 32/3.
41) The given equation is: 
and
So, 
The answer is 23/4.
42) The given equation is 
The answer is 1/12.
3 over 45 because that was the question <span />
